SAMSUNG

SAMSUNG DDR4 2133MHz CL15 16GB RegECC 2Rx4 M393A2G40DB0-CPB desktop RAM

SKU CH-ZEH2-JXNQG

16 GB DDR4 registered ECC module running at 2133 MHz with CL15 latency for server workloads

  • Registered ECC protects data integrity in server workloads
  • 16 GB capacity supports memory-intensive applications
  • DDR4 2133 MHz speed delivers responsive throughput
  • CL15 latency keeps access times low
  • 2Rx4 organisation enables high-density 3DPC configurations

Enterprise RDIMM for Servers

This Samsung DDR4 RDIMM is built for enterprise servers that require registered error-correcting memory. It is not intended for standard desktop motherboards or consumer platforms lacking ECC support. Buyers who need unbuffered non-ECC modules for a typical PC should look elsewhere. The module targets administrators configuring qualified server hardware.

Registered ECC with 2Rx4 Organisation

The single specification that determines compatibility is the registered ECC design with a 2Rx4 layout running at 2133 MHz and CL15 latency. Only systems that explicitly support registered DIMMs and the x4 rank structure can use this module. Standard consumer chipsets will not initialise it, so verifying the server configuration is mandatory before purchase.

No Bundled Accessories or Software

The product ships as a bare memory module without cables, brackets, software licences or documentation beyond the manufacturer label. Nothing in the bundle changes the installation procedure or enables features the server firmware does not already provide. Administrators simply insert the DIMM into a qualified slot and configure the BIOS.

Questions about this item

What does the 2133MHz rating mean once the module is installed in a server?

The module runs at 2133 MT/s, delivering PC4-2133 bandwidth for registered ECC workloads in compatible server platforms.

How does the registered ECC interface affect usable capacity and error handling?

The RDIMM adds a register and 8-bit parity for ECC, enabling 2Rx4 organisation and up to 3 DIMMs per channel on supported server motherboards.

What physical slot and form factor does the M393A2G40DB0-CPB require?

It uses a standard DDR4 RDIMM 288-pin form factor and fits server DIMM slots keyed for registered memory.
